Ich kann nicht zwei Objekte in der Rails-Konsole verbinden manuell einen NoMethod Fehler

Question

Also ohne immer ich habe 2 Modelle:

User.rb

class User < ActiveRecord::Base 

    has_many :pics 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
    :recoverable, :rememberable, :trackable, :validatable 
end 

Pic.rb

class Pic < ActiveRecord::Base 
    belongs_to :user 
end 

Sie sind jeweils durch eine Eins-zu-Viele-Verknüpfung verknüpft. Ich kann jedoch nicht zwei Objekte in der Rails-Konsole zuordnen, ohne einen NoMethod-Fehler zu empfangen:

2.3.0 :001 > @user = User.first 
    User Load (0.2ms) SELECT "users".* FROM "users" ORDER BY "users"."id" 
ASC LIMIT 1 
=> #<User id: 1, email: "nono@gmail.com", created_at: "2016-12-20 
10:52:10", updated_at: "2016-12-20 10:52:10"> 
2.3.0 :002 > @pic = Pic.first 
    Pic Load (0.1ms) SELECT "pics".* FROM "pics" ORDER BY "pics"."id" ASC 
LIMIT 1 
=> #<Pic id: 1, title: "Yo! My first post!", description: "Wazzaaappp this 
is Wali", created_at: "2016-12-20 10:30:45", updated_at: "2016-12-20 
10:30:45", user_id: nil> 
2.3.0 :003 > @pic.user = @user 

NoMethodError: undefined method `user=' for #<Pic:0x00000002918758> 
Did you mean? user_id= 
    from /usr/local/rvm/gems/ruby-2.3.0/gems/activemodel- 
4.2.5/lib/active_model/attribute_methods.rb:433:in `method_missing' 
     from (irb):3 

EDIT: Das ist mein schema.rb

ActiveRecord::Schema.define(version: 20161220102651) do 

    create_table "pics", force: :cascade do |t| 
    t.string "title" 
    t.text  "description" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    t.integer "user_id" 
    end 

    add_index "pics", ["user_id"], name: "index_pics_on_user_id" 

    create_table "users", force: :cascade do |t| 
    t.string "email",     default: "", null: false 
    t.string "encrypted_password",  default: "", null: false 
    t.string "reset_password_token" 
    t.datetime "reset_password_sent_at" 
    t.datetime "remember_created_at" 
    t.integer "sign_in_count",   default: 0, null: false 
    t.datetime "current_sign_in_at" 
    t.datetime "last_sign_in_at" 
    t.string "current_sign_in_ip" 
    t.string "last_sign_in_ip" 
    t.datetime "created_at",       null: false 
    t.datetime "updated_at",       null: false 
    end 

    add_index "users", ["email"], name: "index_users_on_email", unique: true 
    add_index "users", ["reset_password_token"], name: 
    "index_users_on_reset_password_token", unique: true 

end
